"the insulation they recommended saved me about 5000kw a year. the amount of money i am saving is far more the insulation payment on my Eversource bill. No money cost to me out of pocket and my electric bill dropped quite a bit. best move i ever did."

"Vista has come to our house, especially a particular gentleman. Really knowledgeable, very professional. They do several different things. I have had them out to do estimates on gutters. We have not hired them for anything. To give you an idea, when they've come out I was very happy to open the door and see it was the same guy that has come several times to do several things. I interview several people. Not only did he come, and it's a little confusing to me because it has to do with ventilation and insulation, and excuse my language but there is a whole freaking science to this thing, but the owner actually came out. Not only did they keep in communication by computer, the owner actually came out and reinforced the whole education and what needs to be done. I was really thrilled with that. I thought that was beyond the call of duty. I am sorry I was not able to go with them, but I would certainly say as far as customer service relationship, excellent. The information was excellent. Not bothered by the fact that he had to come out more than one time for the same kind of information. I've never had the opportunity to hire them. But I've never been disappointed. They will take the time, they will talk to you, they will educate you, and they will actually give you the best price they can possibly give you. I got educated so that when my  husband came home I could explain to him what is going on. I can't rate their work, but as far as their generosity of time and caring, it's off the charts. I don't know about price because this is a whole new area to me. They were amazing. I have to tell you I have had them out several times as I said, it's Vista Home Improvements so they do several things, but I feel kind of bad that I am yet to hire them. I am trying to think exactly where Vista is out of, but for the owner to com about to your house. We're talking about a wrap around attic. We are talking about getting on your hands and knees and crawling around."

"Dirk started the job of renovating in November of 2013. He did everything from removing all wallpaper from the walls, mold treatment , repainting with special paint to keep the mold from returning, to finishing the ceilings, to taking all of the windows ( 8) out, stripping repainting, repositioning, redoing the kitchenette from top to bottom, renovating both bathrooms, replacing part of the ceiling, cleaning the chimney, refinishing the mantelpiece, putting on new chimney caps, renovating all doors, replacing part of an outdoor door frame, putting on a new gutter, power washing the cottage, painting/putting up new shutters, fixing the siding, insulating the water pipes and small cupboard where they come into the structure...
It took him a year to finish the whole structure. Mind you he did all the work himself. He does/did not have a crew of workers with him.
Dirk works meticulously. His work is of an outstanding quality, no cutting corners anywhere, which sometimes may take longer timewise, but the end result is top notch and will not need any retouching for at least a couple of years.
I highly recommend him, especially if you want a top quality job. There are very few things that Dirk is not able to provide. 
I will most certainly hire him for future jobs, whether it will be for outside work or inside work.

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation questions, answered by experts

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.

Upgrading insulation offers several benefits, including improved energy efficiency, which leads to lower heating and cooling costs. It also enhances indoor comfort by regulating temperature and can provide noise reduction. Additionally, better insulation has a reduced environmental impact and can increase your home's value and overall livability.

Garage doors that are not insulated can be a major source of heat loss. That’s why it’s essential to winterize your garage door with insulation and weather stripping to prevent heat loss and keep it warm more easily. Consult a local garage door installer if you need help determining the cause of your garage losing heat.

It's essential to use insulation materials specifically designed for air ducts. Common types of duct insulation materials include fiberglass, foam board, and reflective foil. These insulation materials have the right properties to withstand the temperature and airflow conditions within the ductwork. Using the appropriate insulation not only ensures efficient temperature control but also prevents potential safety hazards or the release of harmful particles into the air.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.
